Plz plz me jamie needs to determine the distance across a river. she selects a rock, r, on the opposite river bank. she finds a tree, t, on her side of the river such that is perpendicular to the river. next, jamie walks 50 yards down the river from the tree, t, to a spot, c. using a compass that she made from two sticks, she measures . she then walks from c in a direction that makes the same angle as with the river bank on her side of the river. she keeps walking in that direction until she sees the tree and the rock in a straight line from her position. she marks this point b and then paces from b to t to measure the distance from point b to the tree. if bt turns out to be 75 yards, what is rt, the distance across the river?

What expression is equivalent to 1/2(2+3x-6)

The graph shows the charges for a health club in a month. make a function table for the input-output values. writes an equation that can be used to find the total charge y for the number of x classes

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
